Methanol → 2-Ethyl-4-{[6-(methylsulfonyl)pyridin-3-yl]oxy}aniline

Participants

Reaction Steps

A mixture of 5-(3-ethenyl-4-nitrophenoxy)-2-(methylsulfonyl)pyridine (5.0 g), 10% palladium carbon (1.0 g, containing water (50%)), tetrahydrofuran (100 mL), and methanol (50 mL) was stirred under a hydrogen atmosphere (balloon pressure) at room temperature for 3 days. The catalyst was filtered off, and the obtained filtrate was concentrated under reduced pressure. The obtained crude product was subjected to silica gel column chromatography (ethyl acetate:hexane=25:75 to 60:40, volume ratio) to give the title compound (4.05 g, yield 89%) as a pale-yellow oil.
